Maximum operating temperature is defined as that temperature which, if exceeded for extended periods, could result in premature unit failure. This data is provided for user reliability information. This may or may not represent the maximum temperature for electrical parameter specifications. Note: Care should always be taken to effectively ground the case of each unit. 2. Specifications are guaranteed when tested in a 50 Ohm system. Specifications indicated as typical are not guaranteed.
